-tum n or (rare) m (strong, genitive -tums or (less common) -tumes, plural -tümer)

1. A suffix used to derive abstract nouns: -dom

• Generally neuter. The masculine only lingers in a few isolated cases, most notably Irrtum and Reichtum.

Nominalization of -tum (neuter singular forms of -tus (forming possessive adjectives)); the process from adjective to noun can still be seen in arbustus (“planted with trees”) → arbustum (“a place planted with trees, orchard”). Later widely supplanted by collateral -ētum. salictum/salicētum might suggest that other derivatives have been leveled through -ētum.

-tum n (genitive -tī); second declension

1. (horticulture) used to form nouns from certain plant or tree names to denote a place where the species grows or is made to grow; grove, thicket, woods; orchard, plantation, -yard, garden

   ‎cārex (“sedge”) + ‎-tum → ‎cārectum (“a sedge-bed”)

   ‎frutex (“a shrub”) + ‎-tum → ‎frutectum (“a shrubbery, thicket”)

• -ētum
• -ctum

-tum

1. inflection of -tus (forming participles and possessive adjectives):
   1. masculine accusative singular
   2. neuter nominative/accusative/vocative singular; often substantivized:

   ‎fūr + ‎-tum → ‎fūrtum

   ‎iubeō + ‎-tum → ‎iussum

From -tus (forming action nouns).

-tum

2. suffix forming the accusative supine of verbs

-tum

1. accusative singular of -tus

See the etymology of the corresponding lemma form.

-tūm

1. accusative singular of -tūs

• -tem (still optionally in a few cases), -tom (obsolete)

From Middle High German -dūm, -dōm, West Central German variant of -tuom, from Proto-Germanic *-dōmaz. The modern -t- is generalized from position after voiceless consonants, likely reinforced by German -tum (but cf. similarly Dutch -te). The modern -u- must also be influenced by German. (While it could be native per se, the lack of an according plural *-timer makes this unlikely.)

• IPA^(key): [tum], (after an unstressed syllable) [ˌtum]

-tum m (plural -temer)

1. nominal suffix: -dom
